The first thing Mac users should be aware of is that there's nothing eye-popping in Snow Leopard that's going to have you scrambling to upgrade. With Snow Leopard, Apple has streamlined and simplified the process of installing Mac OS X. While older versions of OS X made you decide what kind of installation you wanted to perform before you even specified what to install, Snow Leopard's installer gives you a single installation path. Apple has probably ended support for Mac OS X Snow Leopard 10.6.
oh WOW, i can't believe how stupid some of these reviews are. they're trying to open this on windows, even though this SPECIFICALLY says "Mac OS X".
